The Accelerated Weathering Tester is designed for testing materials by reproducing the damage caused by weathering. The effects of sunlight is simulated with fluorescent ultraviolet lamps, and dew and rain is simulated by using condensing humidity.

The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV UV tester can reproduce the damage that occurs over months or years outdoors.
To simulate outdoor weathering, the QUV teste
